  1. 1. Hidden Markov models Identification, control and inverse filtering

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Robert Mattila; Bo Wahlberg; Eric Moulines; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. LÄS MER

  2. 2. Real-Time Workload Models Expressiveness vs. Analysis Efficiency

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  3. 3. Identification of Stochastic Nonlinear Dynamical Models Using Estimating Functions

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Mohamed Abdalmoaty; Håkan Hjalmarsson; Adrian Wills; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction Error Method; Maximum Likelihood; Data-driven; Learning; Stochastic; Nonlinear; Dynamical Models; Non-stationary Linear Predictors; Intractable Likelihood; Latent Variable Models; Estimation; Process Disturbance; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Data-driven modeling of stochastic nonlinear systems is recognized as a very challenging problem, even when reduced to a parameter estimation problem. A main difficulty is the intractability of the likelihood function, which renders favored estimation methods, such as the maximum likelihood method, analytically intractable. LÄS MER

  4. 4. Converting CAD Drawings to Product Models

    Detta är en avhandling från Institutionen för fastigheter och byggande

    Författare :Robert Noack; [2001]
    Nyckelord :Shape recognition; shape interpretation; product models;

    Sammanfattning : The fundamental aim of this study is to examine whether itis possible to automatically convert vector-based drawings toproduct models. The reason fordoing this is that the newobject-based systems cannot make use of the information storedin CAD drawings, which limits the usability of thesesystems. LÄS MER

  5. 5. Textmedierade virtuella världar Narration, perception och kognition

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Ulf Pettersson; Lars Elleström; Paul Tenngart; [2013]
    Nyckelord :HUMANIORA; HUMANITIES; intermediality; virtual worlds; possible worlds; fictional worlds; storyworlds; reader response; semiotics; Gestalt psychology; cognitive linguistics; cognitive psychology; cognitive poetics; reading process; mental models; situation models; schemata; scripts; narratology; diegetic levels; focalization; transactional theory; iconicity; immersion; aesthetic illusion; gaps; concretization; mental places; integration network models; blending; conceptual metaphors; Intermedialitet; läsprocess; mentala bilder; mentala modeller; möjliga världar; fiktionsvärldar; virtuella världar; mentala platser; semiotik; kognitionsforskning; kognitiv semantik; kognitiv lingvistik; kognitiv poetik; narratologi; fokalisering; diegetiska nivåer; luckor; schemata; scripts; estetisk illusion; ikonicitet;

    Sammanfattning : This thesis synthezises theories from intermedia studies, semiotics, Gestalt psychology, cognitive linguistics, cognitive psychology, cognitive poetics, reader response criticism, narratology and possible worlds-theories adjusted to literary studies. The aim is to provide a transdisciplinary explanatory model of the transaction between text and reader during the reading process resulting in the reader experiencing a mental, virtual world. LÄS MER
